Just a little while ago, I was on Garageband making a ringtone with my speakers maybe 1-2 notches below half way, and all of the sudden I heard a sort of POP noise and then the speakers stopped working. I went to itunes and started playing a song and right when the music should have started playing, I heard another POP, and when I paused it there was another popping noise. I have no idea what this is? I couldn't have blown the speakers because it wasn't even turned up half way...Any help, guys?
